budget_set_ceiling

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description fully covers behavioral traits: immediate effect, denial of future budget_spend calls if lowering below current spend, unblocking on raise, requirement for positive integer, and audit logging. No contradictions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and informative, though slightly verbose at ~120 words. Every sentence adds value, but some trimming could improve conciseness without losing clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description fully covers return values and error format. It addresses preconditions, side effects, and operational warnings, making it complete for safe usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but the description adds meaning by clarifying agent_id is for audit, specifying ceiling must be a positive integer (overriding schema's string type), and explaining the effect of setting ceiling. This significantly aids correct invocation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Dynamically change' and the resource 'global token ceiling for all agents.' It distinguishes from sibling tools like budget_reset, budget_spend, and budget_status by explaining its specific role and consequences.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides guidance on when to use (dynamically change ceiling) and explicitly warns against lowering while agents are active, advising to call budget_status first. However, it does not explicitly list when not to use the tool beyond that caution.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
